interesting bag, I wondered if it still had the internal divider and buttons, also the loops sewn on the inside front?
Agree SS Holden maker, there is a clear stamped example here, though his pics are not too close up

funny too, I just picked up another one of these 16 patt bags, mine has been converted also with the addition of a cloth bandoleer strap machine sewn to the back
here is a link to another one I hadhttp://www.cdnmilitarycollectors.com/t2763-wtt-1916-pat-small-pack
